SHIPPING CONTAINER AND PUMP-SECURING MEANS.

Application filed April 18,

This invention relates to an improvement in shipping containers such, for example, as may be employed for the packaging and shipment of oils, greases and the like.

The objects of the invention are, first, to

provide a container having a head fixed thereto and provided with an opening inset from the margin of the head and provided with an improved form of detachable cover; and secio ondly, the invention aims toprovide a head constructed to accommodate the removable cover above referred to and admirably adapted to permit thefasteningv in a quick and satisfactory manner of a pump plate which is adapted to support a pump for the removal of the contents.

The above and other objects are attained by my invention which may be briefly summarized as consisting in certain novel combinations and arrangements of parts which will 'be described in the specification and set forth in the appended claims.

In the accompanying sheets of drawings, Fig. 1 is a sectional view of the upper part of the container' before the cover is fastened in place; Fig. 2 is a view, partly in section and partly in elevation, of the upper part of the container showing the cover secured in place so as to close and seal the container; Fig. 3

and Fig. 4 are, respectively, a perspective view of a hook bolt and a similar view of a wedge utilized in fastening the pump plate to the top of. the container after the cover is removed; Fig. 5 is a side view of thec'ontainer with the pum applied thereto, the plump being supporte on the pump plate which is secured in place in accordance with the present invention; Fi". 6 is an enlarged view of the container with the upper part in section, showing how the pump plate is fastened in position, the pump plate also being in section;` and Fig. 7 is a plan view of the container and pump plate. of Fig. 6, parts being broken away and one of the plate securing wedges being removed.v 5

Referring now to the drawings and first to the construction of the container including the improved removable cover, the body of the container is re resented by 1U and is generally cylindrical.

involved in the present invention. The container body is further provided with a head 12 which is adapted to be secured in the usual way. This head has a depressed portion his body hasa bottom 11 which may be of any suitable form and which is not 1927. Serial N0. 184,472.

which fits with a snug fit inside the top of the container body, and its margin is secured by a double seam with the top edge of the container body. The opening in the head which is adapted to receive or to be closed by the cover is set in from the margin of the cover, i. e., is smaller than the cover, this being, of course, well known in containers for the ship'- ment of certain materials such as oils and paints. The opening in the head is surrounded by an upstanding annular flange 1-3 and this terminates in an outwardly rolled bead 14 which is somewhat below the top of the chime formed at the top of the container. The removable cover 15 has a depressed portion which fits with a snug fit inside-of the upstanding flange 13, and this cover has a marginal flange which extends over the' bead 14. Between this flange and the bead 14 a suitable gasket 16 is provided to form a seal when the cover is secured in place.

The fact that thel flange 13 which receives the cover extends upwardly instead of downwardly as is commonly the case in containers of this kind is important for more than one reason. In the first place, it prevents water and the likewhich may lodge in the head from running into the cover opening and into the body ofthe container, and, secondly it facilitates the use of hook bolts for securing the pump plate in place.

The cover 15 is secured in place and is sealed so as to prevent leakage of the contents of the container by a sealing ring 17 provided with separable ends adapted to be temporarilyT fastenedl togetherA by spot welding, soldering or otherwise. This sealing ring has a flange which extends inwardly over the marginal flange of the cover overlying the bead, and. it also has a continuous down-turned flange which extends downward below the bead 14. To secure and seal the cover, a closing tool is employed which presses the sealing ring downward so as to tightly compress the gasket When it is desired to remove the cover 15, it

is only necessary to separate the ends of the sealing ring and to strip it off. The cover can then be lifted from the head of the container.

As far as I am aware, it is novel with me to secure a cover in this particular way to an upstanding flange inset from the margin of the head. In applying the sealing ring in the manner above described, it is, of course, essential that there be used a closing tool having jaws which will engage the down-turned fiange of the sealing ring and bend inwardly the portions 17a without being interfered with by that portion of the head 12 which lies between the flange 13 and the upstanding chime of the head which surrounds the flange.

The above described construction of the head including the up-turned flange 13 beaded at the top to accommodate and receive the sealing ring is not only of importance in forming a seat for the removable cover but it also permits a pump plate to be readily and satisfactorily secured to the top of the container as will now be described. Y

When containers of this general nature are used for the shipment of oil or grease such as is used in automobile service stations, it is' customary to remove the cover and secure to the top of the container a so-called pump plate carrying the pump by which the contents of the container is adapted to be removedwhen needed. As the containers have been constructed heretofore considerable difficulty was experienced in securing the pump plate in place due largely to the fact that it was necessary to align bolt holes in the pump plate with nuts fixed in the head and provided primarily for the purpose of receiving bolts which were designed to secure in place the removable cover'.

In Figs. 5, 6 and 7, I have illustrated my method of applying and securing the pump plate which overcomes the difhculties heretofore experienced. Y In'Fig. 5, I have illustrated the pump at 19 and in Figs. 5, 6 and 7,

' Ihave shown the pump plate 20 to which the pump is secured, the pump plate being a circular plate adapted to fit over the chime at the head of the container and provided with an opening 21 to accommodate the pump and generally also with another opening normally covered by plate 22 to cage the drip.

Va plurality of openings 28 are provided in the pump plate which, when the pump plate is in place on the container, lie just inside of the upstanding flange 13. In this instance, four of these openings are provided, these being equally spaced but this particular number is not essential. To secure the pump plate in place, I employ so-called hook bolts E24, each provided with a shank which is adapted to be extended through one of the openings 23, the shank having at one end a head 24a which is above the pump plate and having at its opposite end a hook 241 which is adapted to engage beneath the head as illustrated in Fig. 6. That is to say, the shanlrs of the hook bolts extend down through the opening for the cover and just inside of the upst-anding flange 13 and the hooks when in operative position extend outwardly so as to engage the under side ofthe head immediately outside of the cover opening In applying the hook bolts, the hook portions are first inserted through the opening 23 and then the hool; bolts are straightened up and turned part way around so that the hooks will eX- tend outwardly beneath the head.

Additionally, I employ suitable means for tightening the hook/bolts after they have been applied in the manner just stated and in the form of the invention herein illustrated, themeans employed for this purpose consisting of U-shaped wedges 25 which are inserted beneath the heads 24a of the hook bolts as illustrated in Figsy5, 6 and 7. In this way, the hook bolts can be quickly tightened so as to hold the pump plate inplace.V

The use of wedges is preferred over adjustable nuts or equivalent means for not only can the wedges be quickly` applied to tighten the bolts but there isno 'danger of the hook bolts being turned so as to disengage the hooks from the under side of the head.

I previously stated that because the flange which surrounds the cover opening is upturned instead of down-turned, water and other foreign matter are prevented from running into the interior of the container and the application of the pump plate by means of the hook bolts is much facilitated especially because the present construction leaves an unobstructed fiat surface on the lower side of the head for engagement with the lower ends or hooks of the hook bolts. I wish to point .out also that this new construction involving an up-turned flange instead of a down-turned fiange around the cover opening has still another Vdistinct advantage, that advantage being that itis much easier to remove the contents of the container by pouring or otherwise.

Having thus described my invention, I claim:

1. The Combination with a container having a body portion, a head extending inwardly from the upper end of said body portion and having an opening adapted to receive the container' cover, said head having a flat under surface and an inner rim lying below the upper outer margin of the container' when the cover is removed, of a pump plate adapted to extend entirely over the top of the eontainer, a plurality of hooks extending through said plate and said eover opening and having portions adapted to be swung into engagement with said flat under surface, heads on said hooks, and wedge members cooperating with said heads for clamping the plate onto the container.

2. The combination with a container havingr a body portion and an inset head having a cover opening, said head being provided with an upturned rim around said opening and a flat under surface, of a pump plate adapted to extend entirely over the top of the container, and means for securing said plate onto said container, said means comprising a plurality of hooks extending through said plate and said opening for engagement with said flat under surface, heads carried by said hooks and extending above said plate, and means engaging said heads for wedging them away from said plate.

In testimony whereof, I hereunto aflx my signature.

JAMES E. FITZGERALD.
